com.sas.iquery.metadata.business.ModelItem

Packages that use ModelItem

com.sas.iquery.metadata.business.step | Provides a set of modeled "step" operations that can be applied, in a particular order, to data items and business queries to modify the results of a query.
com.sas.iquery.metadata.business.step.olap | Provides a set of modeled "step" operations that can be applied, in a particular order, to OLAP data items and business queries in order to filter the data that gets returned when business queries are executed.
com.sas.iquery.metadata.expr | Provides classes that are used to model expressions, which are used to compose data items and filters.
com.sas.iquery.metadata.expr.olap | Provides classes used to define OLAP expressions usable within a business model for defining portions of an OLAP business query.
com.sas.iquery.metadata.expr.relational | Provides classes that are used to model relational database expressions which are typically used when defining the expression portion of filters.

`interface` | `BusinessGroup` The purpose of this object to allow the ability to group certain IQ objects outside of our normal `MapFolder` structure.
`interface` | `BusinessItem` Specifies a modeled object that has an identity within its model and used directly in forming business queries.
`interface` | `BusinessModelObject` Specifies an abstract, persistable object that is contained within a business model container and provides support for having a unique identity within that container.
`interface` | `BusinessRule` Specifies a modeled action that affects how data is referenced at query execution time.

`interface` | `DataItem` Provides support for the mapping of physical data to a single unit of business data.
`interface` | `DataItemReference` Specifies a reference to a DataItem object along with some set of overridden attributes of the base data item.
`interface` | `DrillThroughToDetail` Specifies a simple business rule that identifies whether the user should be allowed to drill through to detail data in OLAP results.
`interface` | `FilterCascadeRule` This business rule defines the prompt filter dependencies that makes up the cascade.
`interface` | `FilterItem` Contains a single conditional expression which is used to filter data when running a query and typically yields a result set containing less data.
`interface` | `Governing` Specifies a simple business rule that governs or limits the output of a business query when the query is run.
`interface` | `ModelItemWithIdentity`
`interface` | `Prompt` Enables you to specify portions of a business query at the time a query is run.

`class` | `FilterCascade`
`class` | `Lookup` Determines lookup type values that are set on the data item.
`class` | `LookupByDataItem` Defines a `Lookup` that defines the data item it is associated with should be used for retrieving possible filter values.
`class` | `LookupList` Contains a list of `LookupValue` objects that are used for possible filter values for a data item.
`class` | `LookupNotAllowed` Defines a `Lookup` type where looking up values is not allowed.
`class` | `LookupValue` Defines a single lookup value that is used by `LookupList`.
